Abstract
An electric circuit comprises a plurality of high power switching services connected in series and adapted to be controlled to be all conducting or blocking substantially simultaneously act together as a single switch and each holding a part of a high voltage to be held by the switch in the blocking state of the switching devices. Each switching device has an avalanche diode of SiC connected in anti-parallel therewith and adapted to start to conduct current when reverse biased as of a predetermined voltage limit for preventing that the voltage across the respective switching device exceeds such limit.
